SHACKLE.

SPECFICATION forming part'of Letters Patent No. 618,086, dated January 24, 1899.

Application filed December 7,1897. Serial No. 661,055. (No model.) i

T0 a/ZZ whom 'it may concern.-

Be it known that I, CHARLES HAAsE, a citizen of the United States, residing at Monument Beach, in the county of Barnstable and State of Massachusetts, have invented a new and useful Shackle, of which the followingis a specification.

The purpose of the present invention is to improve the shackle or connecting means between an anchor and its cable and between lengths of the cable, so as to admit of the slipping of the anchor at a moments notice without necessitating the loss of the cable. In the ordinary shackle the connecting pin frequently rusts and becomes stuck and cannot be removed, and the slipping of the anchor is frequently attended with loss of time and the entire cable.

One of the principal features of the present invention is to cause the shackle-pin to move with the link, thereby preventing the rusting of the pin, so that it can be unshipped when required at an instants notice, thereby freeing the anchor and resulting in saving that part of the cable not run out.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacricing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure l is an elevation of a shackle constructed in accordance with this invention, parts being broken away. Fig. 2 is a perspective view of the shackle proper. Fig. 3 is a detail view of the link. Fig. e is a perspective view of the connecting-pin. Fig. 5 is a longitudinal section of the shackle, the dotted lines showing the position of the link when turned to bring the notch therein in register with the notch in a shank of the shackle.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.

The shackle l is of ordinary appearance,

and its Shanks have transverselyalining openings 2 to receive the coupling-pin 3, by means of which the link et is attached thereto. A notch 5 extends from a side of one of the openings 2 and increases in depth toward the outer side of the shackle and receives a wooden pin or key G of corresponding taper.

The coupling-pin 3 is round and of a length so as to have its ends come about iush with the outer sides of the shackle and is provided midway of its ends with a longitudinal proj ection 7 of a length corresponding to the distance between the inner faces or sides of the Shanks comprising the shackle. This projection 7 is of a size to pass readily through the notch 5, and upon turning the pin 3, so as to bring the projection out of register with said notch, its end portions will engage with the inner faces or sides of the shanks of the shackle and prevent longitudinal movement or displacement of the coupling-pin.

The link et has openings S at its ends, and one of the openings has a notch 9 to receive .the projection 7 of the coupling-pin,whereby the link and pin move together when the cable is vibrated or handled. This notch 9 is located near one side of the opening S and inclines, thereby admitting of the link at being turned to bring the notches 9 and 5 in register without requiring the outer or free end of the said link 4 to enter the space formed between the shanks of the shackle, as indicated by the dotted lines in Fig. 5.

Then placing the link e in position, it is turned so as to bring its notch 9 in coincident relation with the notch 5, after which the coupling-pin 3 is passed through the alining openings 2 and 8, the projection 7 passing through the notches 9 and 5, and the pin being limited'in its inward movement by the projection 7 engaging with the inner face of the-shank opposite that having the notch 5. Upon turning the link so as to bring the notches 5 and 9 out of register the couplingpin is prevented from displacement. The key 6 is now forced home in the notch 5, and being of wood will not become stuck by cor= rosive action. In order to prevent the jamming of the coupling-pin by the key, the notch 5 is made of dovetail shape, and the key 6 is of corresponding or wedge form. lVhen it is IOO required to slip the anchor, the link fi is turned into the position shown by the dotted lines in Fig. 5, when the coupling-pin can be unshipped by driving thereon, the project-ion 7 engaging with the key 6, loosening and removing the latter.

IIaving thus described the invention,wliat is claimed as new is- 1. In a cable for anchors and the like, a shackle having alined openings in its shanks, and a notch extending from one of said openings, a link arranged within the shackle, a coupling-pin having its extremities fitting in the shackle-openings and also having an interlocking connection with the link,whereby the pin and link will move together and cause the ends of the pin to turn freely in the shackleopenings, and a wooden key registering in the notch in the shackle-shank and forming a noncorrosive temporary closure therefor,substan tially as set forth.

2. The combination of a shackle having its Shanks formed with transversely-ahmed openings and having one of the openings provided with a notch extending therefrom, a link having an opening correspondingly notched, a coupling-pin having a projection adapted to pass through the notch of the shank and interlock with the notch of the link, and a ternporary closure for the notch in the shackleshank, said closure being displaced by the re moval of the coupling-pin, substantially as set forth.

3. In combination, a shackle having its Shanks formed with transversely-alining openings, and having one of the openings provided with a notch extending therefrom, a link having an opening correspondingly notched, a coupling-pin having a projection to pass through the notch of the shank and interlock with the notch of the link, and a key of wood or like material tted into the notch of the shank, substantially as set forth.

4. In combination, a shackle having its shanks formed with transversely alining openin gs, one of the openings having a notch extending therefrom tapering throughout its length and of dovetail shape, a link having an opening provided with a notch near one side of the opening, a coupling-pin having a projection midway of its en ds to pass through the notch of the shank and interlock with the notch of the link, and a tapering key of Wedge fornisecured in the notch of the shank, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence of two Witnesses.
